Dear Oyedeji Kolawole Julius,
Research has show that Macleaya cordata can be combined with with compounds like CTC, Avilamycin, BMD or OTC with very good effects.
Furthermore I would like to point out that dosage is important. The effect of Macleaya cordata is clearly dose-dependent. Higher dosage have a stronger effect than lower dosages, as Dr. Niewold's research paper shows.
If you need more advise on this topic, kindly e-mail at t.steiner@phytobiotics.com.
Best regards
Tobias
